[libvirt] [PATCH] Fix undefined symbol error when macvtap support is disabled

[Matthias Bolte]

Use macvtap specific functions depending on WITH_MACVTAP.

Use #if instead of #ifdef to check for WITH_MACVTAP, because
WITH_MACVTAP is always defined with value 0 or 1.

Also export virVMOperationType{To|From}String unconditional,
because they are used unconditional in the domain config code.
